Description
The Rise Armament RAVE 140 Flat is the second generation of the company's best-selling RA-140 Super Sporting Trigger, and it earns its reputation as one of the most popular drop-in units on the market. You get a fixed 3.5-pound single-stage pull with a clean break, minimal over-travel, and a short reset that resets fast when you're running strings. The flat red trigger shoe gives you a little extra leverage and a consistent finger placement, which pays off when you're chasing tighter groups or trying to shave time on a stage.
What Sets the RAVE 140 Flat Apart
Rise packs the whole fire control group into a housing machined from a solid block of 6061 aluminum, which holds up better over the long haul than stamped or punch-tin housings. The internal parts are cut from S7 tool steel, heat-treated, and finished in black nitride so they shrug off wear and resist corrosion round after round. One of the things folks appreciate most is the NoWay take-up design, meaning there's no slack before the sear engages. Movement starts right at the pull, so the break feels immediate and predictable every time.
Dropping the RAVE 140 Flat Into Your Build
Installation is about as painless as it gets. Pull your old fire control group, set the RAVE 140 into your lower, push the pins through, and reassemble. There are no set screws to torque down because springs on the bottom of the housing handle the tension for you. If you've never swapped a trigger before, this is a great first upgrade since there's nothing to align or adjust.
It fits AR-15 and AR-308 pattern rifles and pistols built to mil-spec small-pin dimensions, covering calibers like .223/5.56, .308, 6.5, and 9mm. Competitors, target shooters, and hunters all get real mileage out of it, and Rise backs the trigger with a lifetime warranty. For the money, it's tough to beat as a step up from a gritty factory trigger.

Frequently Asked Questions
What is the pull weight on the RAVE 140 Flat?
The RAVE 140 Flat comes fixed at a crisp 3.5-pound single-stage pull. It's not adjustable, which keeps things simple and consistent shot to shot. That weight hits a sweet spot for range work, competition, and hunting alike.
Is the RAVE 140 Flat easy to install as a drop-in trigger?
Yes, it's one of the easier trigger swaps you can do. The entire fire control group sits in a self-contained aluminum housing, so you just remove your old trigger, drop this one in, and set the two pins. There are no set screws to tighten since spring tension in the housing handles that for you.
Will the RAVE 140 Flat fit my rifle?
It's built for AR-15 and AR-308 pattern rifles and pistols made to mil-spec small-pin dimensions. That covers common calibers like .223/5.56, .308, 6.5, and 9mm. If your lower is standard mil-spec, this trigger should drop right in.
What's the difference between the RAVE 140 Flat and the Curved version?
The internals and 3.5-pound pull are identical between the two. The Flat uses a straight trigger shoe that gives you a bit more leverage and a consistent finger reference point, while the Curved offers a more traditional feel. It really comes down to personal preference for how the trigger sits against your finger.
